Speed Velocity Acceleration

The difference between speed and velocity is...

• Speed has direction.

• Velocity has direction.

• They are the same thing.

• 1.8 m.s^2

• 11.25 m/s^2

• 5 m/s^s

• 5 m/s

A biker speeds up from 10 m/s to 30 m/s in 10 seconds. What was their average acceleration?

• 20 m/s^2

• 2 m/s^2
